COMBINED PRINTING AND BRONZING-MACHNE Application filed December 5, 1925. Selal'No. 73,304.

This invention relates to an apparatus for printing and bronzing relatively large heavy sheets of cardboard and the like.

.Tn my pending apiiilication Serial No. 686,720 filed January 17, 1924. is disclosed a bronzing machine equipped with sheetfeeding mechanism. including` al board or platform upon which the printed sheets are manually stacked in two laterally adjacent piles, and including` also reciprocating feed rolls operative to act upon the successive sheets of each pile and dcpositthem upon forwarding belts which transport t-he sheets in successive pairs to the gripper cylinder of the bronzing machine.

According to my present invent-ion, the sheets are transferred by simple and efficient mechanism from a printing` press to the platform of the sheet-feeding mechanism of the bronzing machine and are accurately positioned in pairs on said platform for delivery toit-he forwarding tapes by the feed rolls, thereby obviating the necessity of manually transporting stacks of printed sheets from the press to the platform.

My invention comprises novel features of combinations of parts which will be hereinafter fully described; the scope of the invention being defined in the appended claims.

In the drawingsn Figure 1 is a front elevation offa bronzing machine equipped with sheet transfer mechanism embodying` my invention, the printing press and the portion of the transferv mechanism adjacent thereto being omitted.

Referring to the drawings (Fig. 2) designates the sheet carrying cylinder of a bronzing machine; 21 designates the power driven shaft for the'cylinder,and22 des-' ignates the oscillating registering lingers mounted adjacent the p'eriphery'of the cylinder and operable to position the leading edge of a printed sheet inthe path of the usual grippers 23'on the cylinder. The sheet is advanced to the grippers by means of,- forwarding belts 24C, to which the sheets are successively delivered from a platform 2S by means offrictional feed rolls 26 carried by longitudinally reciprocating bars 27 which oi-*erhang'the belts and the platform. The forwarding` belts pass about pulleys 28,

29 mounted on suitallv-disposed cross-slurtls 30, 3l. respectively', one ot which halts is mounted adjacent the platform and the other sha'tt adjacent the cylinder 2li. The sha tt lll is provided at one end with a` pullcv 32 which is connected hv nic-aus o't' ay hell'. 33 with a pulley Ill on a driven shail't 35 oli the lufonzingr machine; 'the shal't Il() thus being.;r actuated to drive the bells EB-l with their upper runs` travelling; toward the clvlinder, as indicated.

The bars QT are `jointed to a pair ol arms 36 rising` trom a roclesha'lt Il? having; at one end a c 'ank-arm which connected by means et a rod lill with a wrist pin V'lll on a cam lll on one end oit the cylinder sha li". Hence during the rotation o'l the cylinder the shaft 37 is oscillaled io etlecl the lonpgitudinal reeiprocation ol the bars 2T and their Afeed rolls 2G.

The mechanism above reterred to hein@l described in the copendinn` application tlcrial No. (386.7520 aloresz id, needs no detailed description herein.

Llli designates oscillatory take-ell mechanism, including grippers Ailoperative to grip the upper edge et" each succeeding sheet as rapidly as it printed` and transfor the sheet to a receiving structure on the sumiorting1 traine. These gripper-s are carried bv an oscillatorv arm Lili" which is actuated trom a driven sha'l'ft (ifl of the press through interposed cani and gear noel-fha nisin in the usual manner. The sheet receiving structure, in lieu ol the stationaryT bed heretofore employed. includes an inelined reeirn'ocatineI elevator -ll (Figs. (i and 111i) upon which each succeeding sheet is successiveliv deposited by the rrippers Ll-T, which elevator carries the sheet to a position above. and deposits it upon conveyer tapes lll extending; at right anales to the press. The elevator is a reet-angular structure comprisingtwo end members 50, 51 two side members and a croes-piece oil spaeed trom the lower end member 50. rlhis cross-piece has secured thereto a pair ol spaced-apart strips Vill- 'lformed with annular end port-hans oo which lie adjacent to and. project above the end member dll. and are adapted in the downward motion ot the clevntor to pass under and engage the lower edge of a sheet which has been carried over by the arippers The elevator slid-aldiT mounted. on a. pair ot inclined anglebars 56 `which are atlixed to the main traine el Leanne the press. the upper ends ol the bars being connected bjr a :rossehar 57. rlhe lower ends ol the bars Titi are provided with upwardly and inwardly extending; hracltet members llo. on the l'ree ends ol' which are inclined lingers (ill that are so located as lo receive the trailing; end ot the sheet when the sheet is heine carried over hv the grippers.

(Slee llig. lf3.) Hence in the initial return or down stroke of the elevator' the fingers engage the opposing edge of the sheetv and strip the sheet from the elevator, thuspermitting it. to fall upon the underlying` conveyer tapes 49. (See Figs. 9, 10 and 11.)

As the elevator descends, after the removal of the printed sheet therefrom, the cam 74 impinges against the opposing toe 72 and effects the upward movement of the fingers to position their depending port-ions above the path of the next succeeding sheet on the elevator when the latter again moves upward. (See Fig. 10.)l

It is to be noted that the lower end bar 50 of the elevator is suitably notched at spaced intervals, as at 76, to permit the end bar to clear the fingers when the latter are in their down or sheet-engaging position.

As a simple and eflicient means to cam down any sheet on the elevator that may be curled or buckled, I arrange adjacent the respective ends of the shaft sheet leveling fingers 75 against which bears the top of the progressing sheet. These fingers are preferably composed of suitably shaped wire, one end of each of which is secured to the adjacent bracket 69, the body of the wire being loosely coiled around the rock-shaft and then extended laterally of the shaft and downwardly bowed as shown. These fingers are thus stationary and the rock-shaft, with its stripper fingers, is movable relatively thereto.

The conveyer'tapes 49 upon which the sheets are successively deposited, are supported and guided byk rolls 77, 78 mounted below the respective sides of the elevator. These tapes transfer the sheets to a set of conveyer tapes 79 which lead to the horizontal board .or platform 25 upon which 'the sheets are successively delivered and from which they are fed in an orderly manner to the forwarding belts 24 preparatory to the delivery of thesheets Vto the cylinder of the bronzing machine. The tapes 7 9 pass about the roll 78 and a similar roll S() mounted adjacent the board or platform 25.` The sheets bo-rne by the tapes 7 9 are guided on their passage to the platform of thebronZ- ing machine by parallel side boards 81 which are supported by brackets 82 rising from a suitable frame work 83. Extending along the top of the platform 25 are the upper runs of conveyer tapes 84 which pass about the roll SO at the receiving end Yof the platform, and about a similar roll 85 mounted at the opposite end of the platform. (See Figs. 1 and 7.)

The shaft of the roll 8O bears a bevel gear 86 with which 'meshes a similar gear 87 on one cndof the driven shaft above referred to, and in consequence the roll 8O is rotated and the sets of belts 49.y 79, 84 are concurrently driven in the same direction, as indicated by the arrows, and at the same speed as the forwarding belts 24 of the bronzing machine.

In the present instance the cylinder`20 of the bronzing machine is designed to operate upon two laterally adjacent printed sheets during the rot-ation of the cylinder, vand hence sheet controlling'mechanism is pro-v vided whereby successive pairs of printed sheets are delivered to the conveyer tapes 49 at the printing'press and thansferred thence by the succeeding conveyer tapes 79 84 to the platform and properly positioned on the e latter for delivery to the forwarding belts 24 and in' timed relation to the operation of f the bronzing machine.

a printed sheet imposed on the traveling tapes by the elevator. )When the sha-ft 88 is partially rotated the depending stop pins are raised and the sheet is permitted to travel with the tapes. On one end of the shaft 88 is a ratchet wheel 90 with which engages a pawl 91 on a vibratory lever 92 loose on-the shaft, which lever is connected by means of a link 93 with one arm of abell-crank 94 fulcru'med yon a bracket 95 on the frame of the bronzing machine. The other arm of this bell-crank is connected by means of a link 96 with a crank disk 97 on the driven shaft of the bronzina machine, and7 therefore, in the rotation of the shaft 35 the bellcrank is rapidly oscillated in a manner t0` vibrate the pawl lever 92,*thus effecting the intermittent rotation of the ratchet wheel and the shaft SSbearing the stop pins 89. A back stop pawlv98 engages the teeth of the ratchet wheel 9G. (See Figs. 8 and 14.)

lin

The intermittent rotation of the shaft 88 in relation to the speed of the elevator and to that of the conveyer tapes 49, is such that in each dwell of the shaft 8S a printed sheet is deposited upon the tapes 49 and temporarily arrested by the depending stop pins, and that in each movement of the shaft 88 such sheetis farried by the tapes 49 beyond the tip-swinging stop pins and, coincidentally, a second sheet is depositedon the tapes 49 and carried' thereby beyond the stop pins and spaced from the preceding` sheet. This done, a second set of stop pins is brought into arresting relation to the tapes 49, another sheet is deposited on the tapes, and the `arresting and releasing operations are repeated, and so on. In thisway the operation of the stop pins is controlled by the vchine having a rotatable sheet-receiving cylinder and mechanism for feeding sheets thereto, of a printing press in co-operative relation to the bronzing'machine, sheet conveying mechanism interposed between the said printing press and the bronzing machine, an` inclined elevator comprising an open frame structure to which the sheets are `successively delivered by the printing press and thereby carried to a position above the conveyer mechanism, means for reciprocating the frame structure, a stripper element overlyingy the path of said structure, and means for .actuating said stripper element during the reciprocation of the structure, whereby each succeedingsheet carried upward by the evelator is released therefromy andV deposited on the conveyer mechanism.
